EDWIN BECKVVITH, OF BUTLER, PENNSYLVANIA.

GRASS-MOWER.

SPECIFICATION forming part of Letters Patent No. 255,913, dated April 4,1882, Application filed December 31, 1881. (No model.)

To all zr/Lom it may concern:

Be it known that I, EDWIN BECKWITH, a. citizen ot' the United States ot'America, residing at Butler, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements inGrass-Mowers; and I do hereby declare the following to he a full, clear,and exact description ot' the invention, such as will enable othersskilled in the art to which it appertains to make and use the saine,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form apart ot' thisspecification.

My invention relates to an improvement in grass-mowers; and it consistsin two circular horizontal cutting-blades whose faces nearly touch eachother, the upper one rotating and the lower one stationary. Both bladesare at their cireumferences provided with cuttingteeth, and motion isimparted through any suitable cog and bevel gearing communicating withthe driving-wheels ot' the carriage, as will be more fully describedhereinafter.

The accompanying drawings represent my invention.

Figure l is a plan view; Fig. 2, a vertical longitudinal section,

and Fig. 3 is an edge view.

A represents the carrier ot the cuttingblades, consisting of a straightpiece, a, that terminates at its outer end in a horizontal cirend beingattached to the carriage. Under the piece ct there is to be a pivotedwheel for support of the carrier, turning in all directions with thecarriage. 0n top ot' the piece a is secured another shorter piece, b,whose outer end, e-a holizontal quadranthas its curved side turned outand backward. The pieces a and bare recessed at their outer ends for theadmission between them of two circula-r blades, B B', placedhorizontally, their faces nearly in contact. The under one, B, isrigidly secured on the disk d,

whose circumference extends to the teeth on the blades. Both blades arearmed with teeth formed to cut in one direction only, and the grass whencut is pushed away from the cutterby theroundedelulcot' thepiece b.Through the center of both blades passes a spindle, c, that is journaledin or passed down through the disk d, and passes out through the cornerof the quadrant e, where, by a bevel-wheel and other suitable gearing,it is connected with the carriage driving wheels, which are not hereshown, as they-form no part of this invention. The upper blade, B', isfastened to the spindle and revolves in close proximity to the underone, cutting the gra-ss and flinging it backward.

Having thus described my invention, I claim- In a grass-mower, thecarrier A, composed of the two pieces t b, the part a having its frontend formed into a circular disk, d, which forms a support for thenon-rotating blade B, and the part b, having the quadrant c formed uponit, substantially as shown.

In testimony whereof' I affix my signature in presence of two witnesses.

EDWIN BEGKWITH.
